Are there any alternatives to niacin?

In the Track Your Plaque program, we tend to rely a great deal on niacin. When used properly, 90-95% of people will do just fine and achieve their lipid and lipoprotein goals with the help of niacin, along with their other efforts.

Unfortunately, around 5% of people simply can't take niacin without intolerable "hot flush" effects, or occasionally excessive skin sensitivity--itching, burning, etc.

Why does this happen? These 5% tend to be "rapid metabolizers" of niacin, i.e. they convert niacin (nicotinic acid, or vitamin B3) into a metabolite called nicotinuric acid. Nicotinuric acid is the compound responsible for the skin flush. Most people can slow or reduce the effects of nicotinuric acid by:

--Taking niacin with dinner, so that food slow tablet dissolution.

--Taking with plenty of water. Two 8-12 oz glasses usually eliminates the flush entirely in most people.

--Taking with an uncoated 325 mg tablet of aspirin in the first few weeks or months. Eventually, you will need to revert back to a better stomach tolerated dose of 81 mg, preferably enteric coated. But a full 325 mg uncoated can really help in the beginning, or when you have any niacin dose increases, e.g., 500 mg to 1000 mg.

But even with these very effective strategies, some people still struggle. That's when the question arises: Are there any alternatives to niacin?

Well, it depends on why niacin is being used. If you and your doctor are using niacin for:

Raising HDL--Then weight loss to your ideal weight; reduction of processed carbohydrates, especially wheat products; avoidance of hydrogenated ("trans") fats; a glass or two of red wine per day; dark chocolates (make sure first ingredient is chocolate or cocoa, not sugar), 40 gm per day; fish oil; exercise; other prescription agents (fibrates like Tricor; TZD agents for diabetes; cilostazol (Pletal)). Niacin is by far the most effective agent of all, but, if you're intolerant, raising HDL is still possible through a multi-faceted effort.

Reduction of small LDL--The list of effective strategies is the same as for raising HDL, but add raw almonds (1/4-1/2 cup per day), oat bran and other beta-glucan rich foods like oatmeal. Reduction of processed carbohydrates is especially important to reduce small LDL.

Reduction of Lipoprotein(a)--This is a tricky one. For men, testosterone and DHEA are effective alternatives; for women, estrogen and perhaps DHEA. Hormonal preparations of testosterone and estrogen are stricly prescription; DHEA is OTC. I have not seen the outsized benefits on lipoprotein(a) claimed by Rath et al by using high-dose vitamin C, lysine, and profile, unfortunately. We are clearly in need of better alternatives to treat this difficult and high-risk disorder.

Reduction of triglycerides/VLDL/IDL--I lump these three together since they all respond together. If you're niacin intolerant, maximixing your fish oil can be crucial for reduction of these patterns using doses above the usual starting 4000 mg per day (providing 1200 mg EPA+DHA). Reduction of processed carbohydrates, eimination of processed foods that contain high-fructose corn syrup, and weight loss to ideal weight are also very effective. "Soft" strategies with modest effects include green tea (>6 cups per day) or theaflavin 600-900 mg/day; raw nuts like almonds, walnuts, and pecans; exercise; soy protein.

Reduction of LDL--Lots of alternatives here including oat bran (3 tbsp per day), ground flaxseed (3 tbsp per day), soy protein (25 grams per day), Benecol butter substitute (for stanol esters), soluble fibers like pectin, psyllium, glucomannan; raw nuts like almonds, walnuts, and pecans.

In future, should torcetrapib become available (by prescription), this will add to our available tools for these areas when niacin can't be used. Until now, the alternatives to niacin depend on what you and your doctor are trying to achieve. In the vast majority of cases, HDL, small LDL, triglyceride, etc. goals for heart scan score control can be achieved, even when niacin is not well tolerated.

Is flaxseed oil a substitute for fish oil?


This question comes up so frequently that it's worth going over.

Flaxseed oil is a wonderful oil rich in linolenic acid, which may provide health benefits all by itself. Some authorities have speculated that the substantial reduction in heart attack seen in the Lyon Heart Study, the study that demonstrated the healthy power of the Mediterranean diet, is due to linolenic acid.

Flaxseed oil is also rich in monounsaturates and low in saturates, both desirable qualities. Of course, I'm talking here about flaxseed oil, to be distinguished from flaxseed , which are the intact seeds. The seeds themselves also contain the same oils, but contain other components, specifically lignan, a plant fiber with suspected health benefits like reduction in cancer risk.

Despite all flaxseed oil's wonderful properties, it is definitely not a substitute for fish oil. Why do we use fish oil for our coronary plaque control program (trying to reduce your heart scan score)? Several reasons. Fish oil:

--Dramatically reduces triglycerides, usually by 50% or more.
--Dramatically reduces specific lipoprotein classes like VLDL
--Dramatatically reduces, often eliminates, abnormal postprandial (after-eating) lipoprotein patterns, like IDL (intermediate-density lipoprotein)
--Has been conclusively shown to reduce risk of heart attack and death from heart attack (GISSI Prevenzione Trial).
--Has been shwon to reduce risk of stroke.
--Modifies blood clotting parameters, particularly a 20% reduction in fibrinogen.

Flaxseed oil, or linolenic acid concentrate for that matter, do not accomplish any of these effects, all crucial if you are to gain control over your coronary plaque.

Flaxseed oil and flaxseed remain wonderful nutritional agents for their own reasons. But they will not substitute for fish oil in your program. Only fish oil--the real thing--does the job.

If you have coronary artery disease . . . do you know why?

This conversation is aimed primarily at non-followers of the Track Your Plaque program, because if you were a follower, you’d already know the answer!

I saw a woman in the hospital today. She’d just survived her second heart attack one week earlier. At 51 years old, she was understandably shaken, perhaps terrified. She felt that her future was uncertain and, in fact, had discussed with her husband what he should do to prepare for a future without her.

One week earlier, she’d received three stents that successfully aborted her heart attack. But, as is always the case, the modest delays of ambulance transport, the emergency room preliminaries, then of mobilizing an available cardiologist and catheterization laboratory team, totaled nearly two hours before her stent procedure. Inevitably, a moderate amount of damage had been done to her heart.

Her first “event” had been very similar: very little warning, then 911 and the flurry of activity. Both times, the cardiologists (two different physicians) complimented the patient on her prompt action. Both also called her heart attacks “close calls”.

She defied the odds with two near-death events. So, when I met her a week after her last heart attack, I asked an obvious question: “Has anyone told you why you’re having these heart attacks?”

She looked completely puzzled at first. She then said, “No, not really. I just assumed it was genetic. My mother went through the same thing when she was my age. But she didn’t get as far as I have, since they didn’t have these procedures back then.”

To me, this seems inexcusable: This woman had experienced two brushes with death and no doctor had established a cause. Could this woman’s belief be true, that it’s just genetic?

While there are, indeed, genetic causes for heart disease, the vast majority of these genetic causes are 1) identifiable, and 2) correctable. Genetic does not necessarily mean hopeless. It just means that the usual equation of heart disease risk management (heart disease = LDL cholesterol = need for Lipitor) has limited value. It would be like giving penicillin to people for any and all infections. It will work occasionally, but it will fail miserably in a great many cases. Treating LDL cholesterol with statin drugs is just like that.

Perhaps this woman has lipoprotein(a), a serious genetic trait that predicts heart disease at a young age and is largely unaffected by statin drugs. Or, she may have a severe excess of small LDL, only partially suppressed by statins. If she has the combined pattern of lipoprotein(a) and small LDL, that means she has two statin-unresponsive and significant genetic traits. But they respond to niacin, specific nutritional strategies, and several other agents.

The message: If you have coronary disease, you need to insist on knowing why. “It’s genetic” is not an acceptable answer. “There’s no proof of any heart disease causes beyond cholesterol” is also nonsense. “Everyone gets heart disease, or “hardening of the arteries”, eventually. You just got it a little before everyone else” is also patently ridiculous.

Identifying the causes of your coronary disease (or coronary plaque if you’ve had a CT heart scan) is the first step in developing a program of treatment that provides you with control over this disease.

Have you tried inulin yet?

If you haven't yet tried it to facilitate weight loss, it's really worth giving the new inulin-containing product, Fiber Choice "Weight Management", a try.

Recall (from a prior Heart Scan Blog) that inulin is a vegetable-based fiber found in celery, green peppers, etc. that, when exposed to water, expands to many times original volume. This simple phenomenon yields satiety--a feeling of fullness.


The manufacturer of the product has also added green tea, which has been shown in two small clinical studies to enhance weight loss, though by a different route.

We've been advising patients to chew two of the strawberry flavored tablets one hour before every meal (or with breakfast if you eat immediately in the morning). You'll be satisfied with less food and you'll experience less intense food cravings.

Though no one so far has achieved a huge drop in weight, it does seem to enhance a slow, gradual weight loss larger than achieved by diet and exercise alone. And it's very safe and inexpensive. If you give it a try to help you lose weight, let us know what kind of results you've obtained.

More on Vitamin D

If you haven't done so already, you should subscribe to Dr. John Cannell's free newsletter on vitamin D issues. His newest issue is available at:

http://www.vitamindcouncil.com/newsletter/2006-aug.shtml

A sign-up to subscribe is available on the same page.

I continue to be shocked and amazed at the prevalence and magnitude of vitamin D deficiency in the people I see every day. It's been a beautiful summer with very little rain. Most days have been in the 70-80 degree range--very comfortable to be outdoors in the sun and getting skin expoxure to activate vitamin D in the skin.

Yet, in the vast majority of people I see, summer blood levels of vitamin D are virtually indistinguishable from winter levels. Both hover around the 30 ng/ml range. Summer levels in Wisconsin people seem to be no more than 10 ng/ml higher than winter levels. This remains true even in people who spend a lot of their day outdoors gardening, walking, etc. wearing shorts and a short-sleeved shirt, i.e. with plenty of skin surface area exposed.

I'm at a loss to explain precisely why. Yes, it is Wisconsin. But a direct sun overhead, 75 degree day should be providing plenty of sun. My suspicious is that a combination of factors are at work: people are not spending as much time outdoors as they claim; they often seek shade; use sunscreen; and they're overweight. (Excess weight decreases vitamin D blood levels dramatically, yet another reason not to get fat!)

Read more about vitamin D by checking out Dr. Cannell's insightful comments on the unfolding vitamin D story. He holds nothing back.

Why not just get "perfect" lipids and call it a day?

What if you achieved the Track Your Plaque lipid targets: LDL cholesterol 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl?

After all, these are pretty stringent standards. Compared to national guidelines (the ATP-III Guidelines of the National Cholesterol Educational Panel), the Track Your Plaque 60-60-60 goals are laughably ambitious. There's a lot of wisdom hidden in those numbers. The triglyceride level of 60, for instance, is a level at which triglycerides become essentially unavailable for formation of triglyceride-containing lipoprotein particles such as small LDL and VLDL.

If you get to the 60-60-60 target, isn't that good enough? What if you just held your values there and went about your business? Will coronary plaque stop growing and will your CT heart scan score stop increasing?

Sometimes it will. But, unfortunately, many times it will not. The experience generated through clinical trials bear this out. Studies like the St. Francis Heart Study and the BELLES Trial both showed that just reducing LDL cholesterol is insufficient to stop plaque growth. Beyond the Track Your Plaque experience, there's no clinical trial experience that shows whether the 60-60-60 approach does any better.

In our experience, achieving 60-60-60 is indeed better than just reducing LDL. That makes sense. Just raising HDL from the average of 42 mg/dl for a male, 52 mg/dl for a woman adds advantage. Compound this with triglyceride reduction from the plaque-creating equation, and you've doubled success.

But there's even more. What if you had hidden patterns not revealed by conventional lipids? How about lipoprotein(a)? Small LDL? Postprandial (after-eating) abnormalities? Hypertensive effects (more common than you think)!

In 2006, stopping the increase in your heart scan score is, for most of us, not just a matter of taking Lipitor or its equivalent and sitting back. For nearly all of us, stopping the progression of your score is a multi-faceted effort.

Hospitals: Then and Now

It's 1920. The hospital in your city is a facility run by nuns or the church. It's a place for the very ill, often without hope of meaningful treatment, but nonetheless a place where surgeries take place, babies are born, the injured and chronically ill can find care. No one has health insurance and there's no Medicare. Everyone pays what they can. The hospital is accustomed to doling out plenty of care without compensation. For that reason, they welcome donations and sometimes will build new additions or other facilities in honor of a major donor.

Volunteeers are common, since the wards are understaffed and generally suffering from a shortage of trained nurses and personnel associated with the church. Drugs, such as they are, are often prepared from basic ingredients in the hospital pharmacy. Product representatives hawking medicines and devices are virtually unheard of.

Though their therapeutic tools are limited, the physicians are a proud group, dedicating their careers to healing. The majority of the medical staff volunteer large portions of their time to care for the poor who come to the hospital with very advanced stages of disease: metastatic tumors, advanced heart failure, debilitating strokes, overwhelming septicemia, etc.

Hospitals are usually governed by a board of clergy and physicians who make decisions on how to apply their limited resources and continually seek charitable donations.


Fast forward to present day: Hospitals are high-tech, professional facilities with lots of skilled people, complicated equipment,and capable of complex procedures. While they still house people with advanced illnesses, the floors are also filled with people with much earlier phases of disease. In general, they do a good job, with quality issues scrutinized by a number of official agencies to police practices, incidence of hospital-related infections, medication errors, care protocols, etc.

The hospital of 2006 is a more more effective place than the hospital of 1920. But its aims and operations are different, also. Though some churches are still involved in hospitals, more and more are owned by publicly-traded companies that answer to shareholders--shareholders who want share value to increase. Though donations are still sought, much of the revenues are obtained by concentrating on profitable, large-ticket procedures. More procedures are often generated by advertising.

Because they operate to generate profits, several hospitals in a single city or region compete with one another. The 21st century has therefore witnessed the phenomenon of hospital-owned physicians: more and more practicing physicians are employees of their hospital. That way, the physician brings all his patients and procedures to his hospital, not to a competitor. The top of the funnel is the primary care physician, who tends to see all disease when it first occurs. The primary care physician then sends the patient to the specialist, who is obliged (by contract) to perform his/her procedure in the hsopital paying their salary.




Representatives from companies manufacturing and selling expensive hospital equipment and drugs are everywhere, falling over themselves to gain attention of the physicians using their equipment and the hospital buyers who make purchasing decisions. Millions of dollars can be transacted with just one sale.

The number of volunteers has dwindled. The poor and uninsured are commonly diverted elsewhere, often to a government-funded, and often second-rate, institution. Hospitals measure success by comparing annual revenues and numbers of major procedures.

The hospital of 2006 is a vastly different place than 1920. If you're expecting charitable treatment, compassion, and selfless care, you're in the wrong century. In 2006, the hospital is a business. You don't expect charitable treatment at Wal-Mart or from your car dealer. Don't expect it from your hospital. They are businesses and you are a customer. Recognize this fact, lose the nostalgia for the hospitals of yesterday, and a lot more will become clear to you.

The dreaded small LDL particle

Brian is a 59-year old landscape architect whose starting CT heart scan score was 276.

Brian's food choices at the start were deplorable: a pound of sausage per week, sometimes more; butter on anything and everything; up to two pounds of cheese per week; hot dogs; etc. His lipoproteins were accordingly just as miserable: low HDL, high triglycerides, excessive (postprandial, or after-eating) IDL. Small LDL was a particularly stand-out pattern, with 95% of all LDL particles in the small category.

Brian made a dramatic turnaround in lifestyle and corrected all of his patterns--except for small LDL. After one year, small LDL still occupied 95% of all LDL particles, even though the quantity of LDL had been reduced. In order to help convince Brian that correction of his small LDL was going to be necessary to achieve control oover coronary plaque, I suggested that he undergo another heart scan. His score: 435, or a 57% increase.

Each day that passes, I gain more and more respect for small LDL as a cause for coronary plaque growth. Conventional thought among lipid experts is that small LDL should no longer be a factor if total LDL (e.g., LDL particle number) is reduced. But our experience suggests otherwise: when small LDL persists, we tend to see continued, sometimes frightening, plaque growth.

I therefore asked Brian to intensify his efforts: additional weight loss off his somewhat prominent abdomen (since visceral fat increases small LDL), further reduce wheat products and processed carbohydrates, increase niacin (to 1500 mg per day), and use more raw almonds and oat bran.

Don't let small LDL get the best of you. It is a nasty, sometimes persistent abnormality that has impressive effects on plaque growth.

Winning Through Intimidation

Do you remember the book, Winning Through Intimidation by author Robert J. Ringer?



In his 1984 bestseller, author Ringer details how to succeed in business by overwhelming clients and competition by appearing hugely successful and powerful. Rather than a business card, he'd hand out an elegant book to represent himself. He'd show up in a limousine to a meeting, even when he could barely afford it. He used these tactics, even when he was a small-fry, in commercial real estate and built a successful business following such techniques.

This reminds me a lot of what happens in conventional medical practice: The large and successful hospitals, filled with trained staff and technology, exude legitimacy and success. How can they possibly be wrong? Such overwhelming know-how and multiple levels of expertise mustbe right!

Let's be grateful that we do have access to such high-tech, capable care. Unfortunately, just as Mr. Ringer used deceptive practices to appear something he wasn't, this is also true in hospitals. Not all physicians have your best interests in mind. Their principal concern is how profitable your care can be for them--can you be persuaded to have your stent, bypass, etc.. After all, look around you: Aren't all this equipment and personnel impressive? Aren't you intimidated?

The patient that most recently drove home this issue for me recently was a smart and capable executive who came in for consultation. He had been told by his internist that a surgery (to replace his aorta, a HUGE procedure) was probably necessary. In my view, it was not--his process was simply not that far progressed. The risks for danger over the next several years was virtually nil. Unfortunately, this man, now confused and worried, sought an opinion from the chief of thoracic surgery (in the usual white coat and with professorial demeanor, I'm sure) in a major metropolitan hospital (in Chicago), who promptly rushed him off to the operating room.

The pathology report, cleverly not mentioned in any other of the hospital documentation, showed what I had suspected: this man had mild disease that wasn't even close to requiring surgery. But, with all that technology, $100,000 or so of costs, chief of surgery who looked the part, etc.--they must be right!

Robert Ringer's concepts only ring too true for hospitals and some of the unscrupulous physicians in practice. Don't allow yourself to be intimidated.
Vitamin D: Deficiency vs optimum level

Vitamin D: Deficiency vs optimum level

Dr. James Dowd of the Vitamin D Cure posted his insightful comments regarding the Institute of Medicine's inane evaluation of vitamin D.

Dr. Dowd hits a bullseye with this remark:

The IOM is focusing on deficiency when it should be focusing on optimal health values for vitamin D. The scientific community continues to argue about the lower limit of normal when we now have definitive pathologic data showing that an optimal vitamin D level is at or above 30 ng/mL. Moreover, if no credible toxicity has been reported for vitamin D levels below 200 ng/mL, why are we obsessing over whether our vitamin D level should be 20 ng/mL or 30 ng/mL?

Yes, indeed. Have no doubts: Vitamin D deficiency is among the greatest public health problems of our age; correction of vitamin D (using the human form of vitamin D, i.e., D3 or cholecalciferol, not the invertebrate or plant form, D2 or ergocalciferol) is among the most powerful health solutions.

I have seen everything from relief from winter "blues," to reversal of arthritis, to stopping the progression of aortic valve disease, to partial reversal of dementia by achieving 25-hydroxy vitamin D levels of 50 ng/ml or greater. (I aim for 60-70 ng/ml.)

The IOM's definition of vitamin D adequacy rests on what level of 25-hydroxy vitamin D reverses hyperparathyroidism (high PTH levels) and rickets. Surely there is more to health than that.

Dr. Dowd and vocal vitamin D advocate, Dr. John Cannell, continue to champion the vitamin D cause that, like many health issues, conradicts the "wisdom" of official organizations like the IOM.

    Where I live, it's been around 10 degrees Fahrenheit for about two weeks straight. Probably too cold to lay out in a bathing suit.

    For many of us, supplementation is the only choice.

    Also, don't forget that the majority of people after age 40 have lost much of their ability to activate vit D in the skin.

    I just added his book to my wish list and it will be my next read. I am beginning to wonder why don't we seek to reach serum vitamin D somewhere between 100-150 range. Has there been any research indicating any response to these levels? Even with all the recent research focusing on vitamin D, it would be nice to understand overall health responses at varying degrees of serum content from deficiency to toxicity. We need a wider perspective to draw from.

    BTW, an update: 110 pounds and counting . . . My BMI is about to fall into the normal range and my health has never been better!

    This is an unusual thought. Sitting in front of a very warm and soothing fire last night, I was wondering how my skin reacts to the radiation, aside from the warmth and relaxation benefits.

    My level dropped 20 points when I reduced my intake from 10,000 iu/day to 5,000 /day.  I went back to 10,000 and now I'm at 63 ng/ml.  I'll stick with 10,000 iu unless I exceed 100 ng/ml.

    I wonder if there is not a missing piece to the puzzle of vitamin D deficiency in relation to adequate iodine levels.  I have appended text from the website Iodine4health.  In it Dr. Vickery noticed a connection between the two:

    ”I have also noted an apparent connection between bringing sufficient iodine to a bromine plugged thyroid, and the vitamin D metabolism of the body. Although I am unaware of the exact mechanism, it seems clear that the calcitonin/parathyroid hormone/Vitamin D/calcium balance in the body changes as people on iodine loading programs often register as vitamin D deficient when they did not previously."

    I believe this to be my case.  I tested my vitamin D levels for years and they were optimal based on Dr. Mercola's recommendations and I supplemented with D in the form of cod liver oil rarely.  Then I started taking iodine and I had such a dramatic improvement in symptoms that I knew I had been iodine deficient perhaps my entire life.  After 2-3 years of iodine supplemention I am going to get my D levels tested soon.

    Have an observation using a vitamin D light that I thought to mention.  I take vitamin D capsules and have been doing so for around 5 years.  This winter I decided that I would also use a vitamin D3 light pretty much each day in addition to taking the capsules.  I bought a light sold on Dr Cannell's sight.  I've noticed that sunlight and the artificial D3 light makes me feel warm through out the day, something D3 isn't able to do for me, at least.  And with this cold fall/winter going on right now, this 10 minutes of sunlight is a big plus!    

    Well, there might be a nice bonus from using the light.  I think I'm growing bigger, in a muscular way.  I do work out at a gym and have done so for over 1 years.  Just began the slow burn process last week.  But this muscle growth seems to have started around the time I made a conscious effort to use the indoor light or obtain some sunlight.  

    Anyway, no way to prove, and could be completely wrong about this.  Just something I've noticed as my shirts have grown tighter over the last couple months.  Weight has gone up also by a few pounds. I'm pleased.

    SMK- the test for iodine that we order in our clinic (family practice) is an iodine loading 24 hour urine test.

    patients take 50 mg of iodoral then capture their urine for the next 24 hours to see how much is excreted.

    There is a 2 week prep, though, that helps ensure the test is accurate.

    Dr. Brownstein (?) has several books on the topic. I think he recommends the load testing method in his book, "Iodine, why we need it, why we can't live without it."

    I'll be posting my comments on the IOM report soon, although this sucker is 999 pages long and taking me a while to read.  I don't think it is at all true that it focuses on "deficiency" instead of "optimal levels."  I think it is quite clearly and very explicitly focused on optimal levels.  

    The IOM claims to not have found sufficient evidence to conclude that higher levels are optimal.  Now, I do believe that there is good enough evidence to act on the hypothesis that levels should be above 30 ng/mL, and my impression so far is that there is very little data supporting an argument for >50 ng/mL as some suggest.  That said, I won't be convinced that the IOM is *wrong* that definitive evidence for greater than 20 ng/mL is lacking until I finish reading the report and look at some of the primary references.

    I do think it's important, however, to exercise the freedom to act on hypotheses.  If we needed definitive evidence for everyone we do, our familial relations and whole lives would fall apart.  Still, I think the IOM had a responsibility to assess the quality of the evidence and only solidify what is definitive into recommendations, as long as those recommendations don't preclude the freedom to use higher levels.

    In any case, hopefully I can finish this bad boy in the next week and blog about it.

    I'm more concerned about official organizations going beyond the evidence (eat margarine! eat carbs! avoid saturated fat!) than  being over-cautious when there's not a lot of reliable research.

    One more comment on my apparently deleted comment - there's a possibiliy I never typed in the word verification code, but I believe I did actually post the comment. Sorry, if I did falsely accuse.

    Vitamin D Deficiency, what is the best natural source apart from sunshine to help keep the levels up?

    I just found my new vitamin store. The prices are the lowest I could find. They gave me a free gift of $5.00 with no minimum purchase and I got free shipping! The code I used at checkout is WIR500. Maybe it will work for you too?
